“Core work.” We hear the phrase often, and probably associate it with crunches or similar exercises. In Iyengar Yoga, we attempt to continuously integrate our awareness from the core of our body to the periphery and back again. We do so to cultivate stable attention in movement and a dynamic quality in stillness. In Iyengar Yoga, stability is not a static thing—it is intensely dynamic. And this stable dynamism permeates your entire body, your entire being.
